The Narragansett is about 24" in length.  Made with gold chain and the option of having a black tooth and white pearl or a white tooth and black pearl.  The clasp is similar to the Nico Necklace, where you drop the pearl through the gold ring and can adjust the necklace.  Although the black pearl has no connections with The Pirates of the Caribbean, the shark teeth were really found on the ocean floor by a SCUBA diver who is as witty as Captain Jack Sparrow.
